FASTENING MEANS FOR EIOLDS.

Specification of Letters Patent.

Patented June *7, 1921.

Application fi1ed January 23, 1920. Serial No. 353,427.

Be it known that I, Gnonon R. STRAN, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented new and useful Fastening Means for Molds, of which thefollowing is a specification.

This invention relates to improvements in fastening means for molds, andpertains more especially to means for use not only in forming a tightjoint between adjacent edges of two alined adjoining portions of asheet-metal mold-forming casing for a concrete column but formaintaining said cas ing-portions in alinement at said edges.

One obj ectof this invention is to produce exceedingly simple,adequately rigid and highly efficient fastening means of the characterindicated. 7

Another object is to facilitate the assemblage of the component membersof my improved fastening means and to render said means reliable and notliable to get out of order.

With these objects in view, and to attain any other object hereinafterappearing, this invention consists in certain features of construction,and combinations and relative arrangements of parts, hereinafterdescribed in this specification, pointed out in the claims, andillustrated in the accompanying drawings.

In said drawings, Figure 1 is an outer side view of my improvedfastening means shown applied to adjoining portions of a mold for aconcrete column. Fig. 2 is a vertical section taken along the line 2-2,Fig. 1, looking in the direction indicated by the arrows, and in Fig. 2is shown a portion of a concrete column. Fig. 3 is a vertical sectiontaken along the line 3-3, Fig. 2, looking outwardly. Fig. 4 is ahorizontal section taken along the line %4, Fig. 1. looking downwardly.

Referring to said drawings, 7 indicates two longitudinally adjoininglongitudinal portions of a substantially vertical moldformingsheet-metal casing for a concrete column, and 8 indicates a fragmentaryportion of said column. The casing-portions 7 are arranged edge to edgeand alined as at 9, (see Fig. 4) at their meeting longitudinal edges.Two rigid metal brackets 10 are ar ranged externally of said casing andadja cent the joint formed between said casing portions 7 One of saidbrackets is supported from one of said casing-portions, and the other ofsaid brackets is supported from the other of said casing portions. Eachbracket has a laterally and outwardly offset-portion 12 between itsupper and lower end portions and has said offset portion contoured asrequired to form a substantially horizontal seat-member 13 and anupright abutmentmember 14 extending substantially vertically upwardlyfrom said seat-member and spaced from and facing the casing-portionsupporting said bracket. The 'end portions of each bracket are shownriveted, as at 15, to the casing-portion supporting the bracket, s thatthe bracket is secured to said casingportion below the seat-member 13and above the abutment-member 14 of the bracket. The seat-members 13 ofthe brackets are substantially flush at the top thereof and meet, as at16, (see Fig. 3) at their adjacent or inner side edges. the brackets aresubstantially flush at their inner sides and meet, as at 17, (see Fig.4) at their adjacent edges.

A clamping bar 18 lies on and extends across the seat-members 13 of thebrackets and at its outer side edge extends across the inner sides ofthe abutment-members 14 of the brackets and is interposed widthwisebetween the abutment-member 14 of each bracket and the casing-portions7. Said bar 18 has a clamping jaw 19 overlapping (see Fig. 3) the outerside edge 20 of the seatmember of one of the brackets and also has aportion 21 (see also Fig. 4) projecting beyond the outer side edges 22and 23 of the seat-member and abutment-member respectively of the otherof said brackets. Said bar has a slot 24 which extends longitudinally ofthe projecting portion 21 of the bar and over the adjacent seat-member13 and therefore inwardly beyond said projecting portion,that isinwardly from the outer side edge of said seat-member,and has an outerend wall 25. A downwardly tapering wedge 26 extends through the slot 24and is interposed widthwise between said wall 25 and the last-mentionededge and has its upper portion abutting, as at 27 Fig. 1,

against the bracket comprising said seat-- member at the top of theoffset portion 12 of the bracket. Obviously upon driving the wedgetightly into place between the outer end wall 25 of the slot 24 and theadjacent bracket the seat-members 13 and also the abutment-members 14 ofthe brackets are The abutment-members 14 of clamped together at theiradjacent edges, by and between said wedge and the jaw 19, and therelative arrangement of the parts is such that when the brackets areclamped together a tight vjoint between the adjoining casingportions 7has been formed and maintenance of the alinement of said casing-portionsis insured. The jaw 19 has an arm 28 overlapping the under or outersides of the seatmembers 18 so as'not only to prevent upwarddisplacement of said bar upon theassemblage of the component parts of my1mrequired to form an abutment-member spaced from and facing thecasing-portion supporting the bracket, of a bar which is interposedwidthwise between the abutmentmember of each bracket and saidcasingportions and extends across the inner side of said abutment-memberand has a jaw overlapping an outer edge of one bracketand also has aportion projecting beyond an outer edge of the other bracket, said barhaving a slot which extends longitudinally of and inwardly from saidprojecting portion and has an outer end wall, and a wedge engaging saidslot and interposed widthwise between said wall and the adjacentbracket,

the aforesaid jaw having an arm overlapping the outer sides of theofiset portions and outwardly offset portion comprising a' seat-memberat the lower end of said portion and an abutment-member which facestoward and is spaced from the casing, and the brackets being in contactwith each other, of a bar which is interposed widthwise between theabutment-member of each bracket and the casing-portion supporting thebracket and has a aw at the outer side edge of the seat-member of onebracket and a portion projecting beyond the outer side edge of theseat-member of the other bracket, said bar having a slot which extendslongitudinally of and inwardly from said projecting portion and has anouter end wall, and a wedge engaging said slot and interposed widthwisebetween said wall and the offset portion of the adjacent bracket, theaforesaid jaw having an arm overlapping the under sides of theseat-members of the brackets, and each bracket being secured above andbelow its offset portion to the casing-portion supporting the bracket.

In testimony whereof, I sign the foregoing specification, in thepresence of two witnesses.
